The Streetsville Derbys were a Canadian Junior "A" ice hockey team from Streetsville, Ontario, Canada. They were a part of the Ontario Junior Hockey League in 2011 when they merged into the Cobourg Cougars.
The team was briefly renamed the Mississauga Derbys for the 1992-93 season. Streetsville claimed the Central Junior "B" Championship in 1976, 1977, 1978, 1979, 1980, 1983, 1984 and 1986, as well as the 1979 Sutherland Cup as All-Ontario Champions. The Derbys were the hosts of the Royal Bank Cup 2006, the National Junior "A" Championship. At the end of the 2007 season, it was announced that the Derbys would be moving to a new location, Westwood Arena in Rexdale, Ontario. It is unknown if there will be an applicable name change.
In 1986, the Ontario Hockey Association, concerned with growing violence in hockey, suspended the Streetsville Derbys and the Brantford Classics from playing in the 1986-87 season. The suspension of the Derbys had to do with a stick-swinging incident in the final game of the league quarter-final against the Nobleton Devils. A Nobleton player was struck in the back of the head with a two-hand slash, which also struck a linesman and cut his eyelid.
In March 2011, the Streetsville Derbys merged into the Cobourg Cougars and ceased to exist as members of the OJHL.
